Overview

OAuth allows your users to access your web application by verifying their Whop purchases. Think of it as a digital doorman that checks if users have the right credentials before letting them in.

​
Implementation Steps

  1. Send users to an authentication link with your OAuth client ID (found here)
https://whop.com/oauth/?scope=openid+user&response_type=code&client_id=[YOUR_CLIENT_ID]&redirect_uri=[YOUR_REDIRECT_URL]
  1. Get token
export default function Callback() {
  const params = new URLSearchParams(window.location.search);
  const code = params.get("code");
  // Use this code to get an auth token
}
  1. Exchange the code for an auth token:
const getAuthToken = async (code, clientId, clientSecret, redirect_uri) => {
  const response = await fetch("https://api.whop.com/v5/oauth/token", {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      code,
      client_id: clientId,
      client_secret: clientSecret,
      redirect_uri,
    }),
  });
  return response.json();
};
  1. Retrieve profile details
Use the token to get user information: 
const checkAccess = async (accessToken) => {
  const response = await fetch("https://api.whop.com/v5/me", {
    headers: {
      Authorization: `Bearer ${accessToken}`,
    },
  });
  return response.json();
};

Error Handling

Common error codes:
  • 400: Invalid or expired authorization code
  • 401: Invalid access token
  • 404: Incorrect API endpoint

​
Next Steps

  • Store the auth token securely (cookies/session)
  • Implement token refresh logic
  • Add error handling for failed authentications
  • Consider adding a “Login with Whop” button
